The energy-saving performance of commutating fin is analyzed and studied. The prediction of the energy efficiency are based on CFD method. The hydrodynamic performance prediction method for analyzing the interaction between hull and propellers and rudder is studied. The compare results of calculation results and experimental results show that the method has a better precision. Then, the hydrodynamic performance of ship hull with propeller and rudder and commutating fins are predicted by the same method. By comparing the thrust of propeller, the propeller absorbs the same torque with commutating fins and without commutating fins. The energy-saving effect of commutating fins could be gotten. By the method, the commutating fins are got which has better energy-saving effect and the energy-saving effect is 3.41%. The results show that the commutating fin has a good energy-saving effectiveness and the research of ship energy-saving device method is feasible.
